If a doe is in estrus is her urine brown and when she is not it's yellow?
Was out today and that is the question I came up with - would be 2nd rut - had 8 does run at me and stop all around me, 16 eyes knowing something was up, they finally freaked and left, virtually surrounded me in a cirle.
Opted to take the Summit climber instead of the Lone Wolf Alpha and made the wrong decision as it SWEEKED as I stood up - never again with the Summit. 0 degrees this morning and no oil.

Good grief it SQUEAKED - even that spelling looks wrong to me

Nope. Estrous pee and nonestrous pee look the same.
Try flemening.

Killdeer- My mom always told me if I made that face it would get stuck that way!

I found some brown urine the other day as well????

I've always been led to believe that estrus doe urine has a reddish/rose tint to it when you see it in the snow. Not sure if that is fact or not.

I think Steve could have given us more info (rather than smart comments) he is a wildlife biologist.
Seems kind of strange dark brown pee, you would think it would be consistent from one deer to the next. Maybe someone will know the answer, you can't find anything on the internet with everyody speaking of "Scents". I posted on a UK biology forum and no response yet (they are stumped too)

Is it possible that berries or rhubarb in the diet caused the brownish urine? Natural dyes in food can be passed as brown instead of yellow.

Blood turns brownish after it gets old, and old blood in the urine can turn the fluid brown. A urinary tract infection, or urologic surgery, can result in this leftover, old blood.

The following medical conditions can result in dark or brown urine in us two-legged mammals:

-Liver ailments, particularly cirrhosis and hepatitis

-Tyrosinemia, a rare genetic disorder: elevated blood levels of tyrosine, an amino acid

-Acute glomerulonephritis, which is a kidney malady that impedes a kidney's ability to remove excess waste and fluids

-Bleeding in the kidney, ureter or bladder

-Hemolytic anemia (abnormal breakdown of red blood cells)

-Serious muscle injury

-Melanoma (causes a dark brown or even blackish color)

-Copper poisoning

I had always held the theory of bloody urine being from an estrous doe to be suspect. A lot of people confuse estrus with mensus. I asked 4Nolz about deer this year, and he told me that the estrus discharge in a deer is clear. I figured a veterinarian would be a good source.

Yeah, I think the brown is more of a diet or health issue too.

"Capture myopathy is a syndrome of acute or chronic degradation resulting from stressful activity such as a pursuit of the susceptible animal. It can occur without exercise (animal does not have to be chased). Capture myopathy can occur both during physical and chemical restraint. It occurs in most animals, but especially in ungulates. It has been reported in birds and even fish.

Fear and anxiety plus excessive body heat plus too much adrenaline will result in capture myopathy.

The clinical signs of capture myopathy include sudden death within 24 hours, depression, rapid shallow breathing, and failure to recover from anesthesia. Death can occur after several hours of symptoms, or from cardiac arrest. The animal may also appear to recover, but has heart damage. It may die at the next stressful event.

Other symptoms include stiffness or lameness, swollen muscles and brown urine (due to myoglobin excretion which may lead to damage of the kidneys)."

That brown urine in the bottles (tinks, others, ...) I believe also has some poop in it, makin it discolored more brown.

Killdeer I think a Vet is a great source
Tony good info, no surgery has been done on the deer in my area (funny huh). The capture mypothy - that link shows 20% of adult deer die from it (that high?, if so, there will be alot of dead deer where I have been hunting.
Interesting that diet can change the color.
The tinks products and others I have heard have crap in them making it that color - catching it through a mess floor (I know nothing about that business) just rumors.
Really did seem likely that brown pee was a hot doe - sounds good anyway
